Romulus faithfully fulfilled the vow which he had made to Jupiter. On the return of the army to Rome, the soldiers, by his directions, cut down a small oak-tree, and trimming the branches at the top, and shortening them as much as was necessary for the purpose, they hung the weapons and armor of Acron upon it, and marched with it thus, in triumph into the city. Romulus walked in the midst of the procession, a crown of laurel upon his head, and his long hair hanging down upon his shoulders. Thus the victors entered the city, greeted all the way by the shouts and acclamations of the people, who had assembled,--men, women, and children,--at the gates and upon the tops of the houses. When the long procession had thus passed in, tables for the soldiers were spread in the streets and public squares, and the whole day was spent in festivity and rejoicing. This was the first Roman triumph,--the original model and example of those magnificent and imposing spectacles which in subsequent ages became the wonder of the world. The spoils which had been brought in upon the oak were solemnly set up, on one of the hills within the city, as a trophy to Jupiter. A small temple was erected expressly to receive them. This temple was very small, being but five feet wide and ten feet long. A short time after these transactions two other cities were incorporated into the Roman state. The name of these cities were Crustumenium and Antemnæ. Some women from these cities had been seized at Rome when the Sabine women were taken, and the inhabitants had been ever since that period meditating plans of revenge. They were not strong enough to wage open war against Romulus, but they began at last to make hostile incursions into the Roman territories by means of such small bands of armed men as they had the means of raising. Romulus immediately organized bodies of troops sufficient for the purpose, and then suddenly, and, as it would seem, without giving the kings of these cities any previous warning, he appeared before the walls and captured the cities before the inhabitants had time to recover from their consternation.
